Analysis of Energy Saving Design of Indoor-heating and
Wall-insulation Used in Green Buildings
Abstract:
Indoor heating and wall insulation systems are vital parts
in building energy saving designs. Based on the analysis of impact factors related
to the energy saving design of indoor heating and wall insulation systems, this
study adapted the variation of room temperature as the performance index of
energy saving design. A calculation model of energy saving design was established
based on heat balance theory. Using the proposed model, the variation curves
of room temperature with time and the sensitivity of room temperature on various
technical factors were analysed incorporating different insulating materials,
thicknesses of insulation layer as well as different temperature and flow rate
of hot water in the boilers. Finally, it is proposed that the design solution
of energy saving system should consider and assess the technical, economic and
environmental factors from the perspective of project life cycle. Results from
the study showed that the simulation of the proposed model was clear and easily
adaptable. The proposed model is capable of providing abundant simulated data
for design personnel to predict the performance of the design and optimise the
parameters. The findings in the study provided theoretical background and routine
for the determination of parameters and design for indoor heating and wall insulation
systems for developing and designing companies.
